However, there has been little information about the surgical strategy for these lesions. Case Description: A 39-year-old male presented with 1 month of left lumbosciatalgia. The magnetic resonance imaging was consistent with either an L4 IDEM neurofibroma or a meningioma. At surgery, we encountered a red-oval encapsulated lesion firmly adhered to the L4 nerve root, which was totally excised along with the root itself. Notably, postoperatively, the patient exhibited no new neurological deficit. Conclusion: IDEM cavernoma is rare but should always be a differential diagnosis for other common IDEM lesions. A total excision of an IDEM cavernoma and sacrification of the involved nerve root seem to be a reasonable option.","thumbnailUrl":"https://sni-digital-videos.s3.amazonaws.com/articles/b8018522-acf3-4860-814b-851b816d9e44/featured/hero-1781558692782.png","publishDate":"2025-04-25T00:00:00.000Z","doi":"10.25259/SNI_227_2025","categories":["Spine","Case Report"],"fullTextUrl":"https://surgicalneurologyint.com/wp-content/uploads/2025/04/13520/SNI-16-152.pdf"}
